Abstract:
Activated carbon has been widely used for adsorption of metal ions from aqueous solution due to its porous properties. This research aimed to study the preparation of activated carbon from rambutan seeds assisted by microwave irradiation with phosphoric acid as an activator. Effects of various parameters were studied including the concentration of phosphoric acid solution, the charcoal per phosphoric acid ratio on the activation, microwave power and irradiation time. The obtained results showed the optimal preparation conditions as follows: the concentration of 40 percent (v per v) phosphoric acid, microwave power of 700 watts, irradiation time of 240 seconds and charcoal per phosphoric acid ratio of 1 per 30 (w per v). The surface properties of the activated carbon were characterized by scanning electron microscope (SEM) and the results showed that the activated carbon contained high porosity. The relatively high iodine adsorption number (IN) (678.14 mg per g), which indicate high surface area and affinity of the adsorbent, was obtained from the activated carbon prepared by this technique. The adsorption efficiency of the activated carbon for copper ions was also investigated using FAAS. The results showed that the activated carbon was able to adsorb copper ions, which was two times higher than that of untreated charcoal in 0.1 N nitric acid. This confirmed the potential use of the mesoporous activated carbon derived from rambutan seeds for the removal of heavy metals from contaminated water.
